HAND-THREADING LOOM-SHUTTLE.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed January 8, 1908. Serial No. 409,862.

To all whom it may concern: Be it known that we, DAVID L. NoRRIs andWILLIAM B. BROWN, citizens of the United States, and residents ofWestminster, in the county of Oconee and State of South Carolina, haveinvented an Improvement in IIand-Threading Loom-Shuttles, of which thefollowing description, in connection with the accompanying drawing, is aspecification,

I like letters on the drawing representing like parts.

This invention relates to loom shuttles, and particularly to shuttles ofthe hand threading variety wherein the filling thread is guided by handinto the delivery eye of the shuttle.

The invention has for its object to provide a novel form of shuttlewhich can be inexpensively manufactured and which has a delivery eye ofsuch a construction that it will not become dethreaded while the shuttleis in use. a

We will first describe one embodiment of our invention and then pointout the novel features thereof in the appended claims.

Referring to the drawings, Figure 1 is a top plan View of one end of ashuttle embodying our invention; Fig. 2 is a side view; Fig. 3 is asection 011 the line aa, Fig. 2 Fig. 4 is a section on theline y Fig. 1;Fig. 5 is a secltion on the line 9ca:, Fig. 1 looking to the ri 1t.

l3 is the body of the shuttle which is made with the usualbobbin-receiving chamber 4 within which the bobbin or filling carrier 5is situated. The shuttle herein shown is formed with the verticallyextending chamber 6 which is connected with .the bobbin-receivingchamber 4 by a thread passage 7, said thread passage having the openthread-guiding slot 8 leading thereinto, the upper edge of the slothaving a flared mouth, as at 9, to facilitate the guiding of the threadinto said slot and thus into the thread passage. The thread delivery eye10 leads from said chamber 6 laterally through the side of the shuttleas usual. The shuttle is also provided with the vertically extendingslot 11 which leads from the chamber 6 towards the side of the shuttlein an inclined direction and which communicates with a horizontal slot30 that in turn communicates with the thread-delivery eye 10.

The features thus far described are such as are fre uently found inhand-threading shuttles an form no part of our present invenof thethread-delivery eye, as at 20.

being sufficient to permit tion. In threading these shuttles the threadis guided into the thread-guiding slots 8 and 11 and from thence intothe transverse slot 30 from which it is drawn into the threaddeliveryeye.

In our improved shuttle the thread-de livery eye is formed by boring orotherwise forming a transverse aperture in the shuttle which leads intothe chamber 6, and the body of the shuttle is cut away on each sideSituated at each side of the eye at its outer end is avertically-arranged pin, said pins being designated 12 and 13. Both endsof the pin 12 enter the body of the shuttle, but a thread passage isformed around the upper end of the pin 13 to permit the thread to bedrawn into the thread-delivery eye, said thread passage being soconstructed as to prevent the thread from being thrown out from thedelivery eye. .To accomplish this the shuttle is formed with atransversely-extending recess 15 which is situated directly over the pin13 and which communicates both with i the slot 30 and with thethread-delivery eye 10. The pin 13 is of such a length that a slightspace is left between the upper end thereof and the wall of the recess,this space the thread to be drawn up over the pin from the slot 30 intothe thread-delivery eye. At the inner end of the thread-delivery eyeanother vertically arranged guide pin 16 is provided around which thethread runs as it is drawn from the delivery eye, said guide pin beinsituated somewhat further from the point of the shuttle than the guidepin 13.

The shuttle is preferably beveled or cut away at 17 at the end of thetransverse recess 15. In threading the shuttle the thread is led intothe thread-guiding slots 8 and 11, and from the slot 11 into the slot30. The thread is then drawn backwardly in said slot 30 until it comesinto the transverse recess 15 and strikes the pin 13. The operator thenlifts the thread against the bevel portion 17 of the shuttle and drawsbackwardly on the thread, as seen in Fig. 2, thus drawing the threadover the pin 13 into the delivery eye.

It will be noted that when the thread has been drawn against the pin 13and is being pulled backwardly, as seen in Fig. 2, the thread makes acomparatively sharp angle around said pin, as seen in full lines Fig. 3,and is thus readily drawn up over said pin. After the thread is drawninto the thread-delivery eye the portion between the ins 16 and 12 liesunder the shoulder 24 forming the edge of the recess 15. After theshuttle has been properly threaded the thread is prevented from beingdrawn out from the delivery eye when said thread is drawn into thedotted line position shown in Fig. 3 partly because the positions of thepin 16 and the end portion 17 of the recess relative to the pin 13prevents the thread from being drawn around said pin at a sufficientlysharp angle to permit the thread to be drawn over the pin, and partlybecause the shoulder 24 assists in preventing the thread from beinglifted high enough in the recess 15 to pass over said pin 13. This formof delivery eye is very simple to manufacture because after the hole isbored to the shuttle the formation of the eye requires simply theinsertion of the two pins 12 and 13, and said pins may be readilyinserted from the bottom of the shuttle.

WVe also preferably provide a friction device in the nature of a feltwasher 31 situated in the bottom of the chamber 6 and in such positionthat the thread is drawn through the same as it is delivered from theshuttle. The felt Washer afi'ords sufficient friction to the thread sothat the latter will be delivered uniformly from the bobbin and a bettergrade ofcloth can be woven.

Having fully described our invention, What we claim as new and desire tosecure by Letters Patent is 1. A shuttle having formed therein abobbin-receiving chamber, a thread-guiding slot leading from saidchamber to the side of the shuttle, a horizontal slot communicating withsaid thread-guiding slot, and a threaddelivery eye extending laterallythrough one side of the shuttle and the horizontal slot, said shuttlehaving a transverse recess situated above said horizontal slot andcommunicating with both said slot and the delivery eye, and a pin at theouter terminus of said delivery eye and forming one side of the latter,said pin extending above the slot and terminating within said recess.

2. A shuttle having formed therein a bobbin-receiving chamber, a chamber6, a thread passage connecting the two chambers and a thread-deliveryeye leading from the chamber 6, an open thread-guiding slot leading intothe thread passage and extending to the side of the shuttle, and ahorizontal slot connecting said thread-guiding slot with thethread-delivery eye, said shuttle having a transverse recesscommunicating both with the thread-delivery eye and the horizontal slot,a vertically-arranged pin 13 at the end of the thread-delivery eye, theend of which pin is received in the transverse recess, and a feltfriction material within the chamber 6.

In testimony whereof, we have signed our names to this specification inthe presence of two subscribing witnesses.
